Quoting Baron Von Ben ~
DDUUDDEEE!!! I made something like this a couple of months ago!! i didn't post it, but it was HUGE! it had TWO of the ramps, but it wasn't motorized...so you beat me there! Love it man.
Really? I knew that I wasn't the first one to do this. I've seen videos of exponentialy more complex versions. However, they have all been system-aided.
